During cold
weather, stage and discharge values may be affected by ice at some
streamgages. Streamgages experiencing ice conditions will have the
discharge record temporarily disabled to prevent the display of
erroneous discharge values. Display of discharge record will resume
when it is determined that ice conditions are no longer present.
Adjustment of data affected by ice can only be done after detailed
analysis.

The 1-hour precipitation data for this station are
temporary and will only be displayed for 120 days. Time series
of 1-hour or cumulative daily values will NOT be available for
retrieval following the 120-day display period. Although the
instrumentation is calibrated at least once a year, the temporary
classification means that documented routine inspections and other
quality assurance measures are not performed that would make the
data acceptable for archival, retrieval, or future use in general
scientific or interpretive studies.
